生物反应器填埋场渗滤液及其处理对策

The Characters and Treatment of Bioreactor Landfill Leachate

根据垃圾的降解和稳定机理分析了生物反应器填埋场渗滤液的动态变化规律 ,并对其处理对策进行了探讨。生物反应器填埋场前期产生的渗滤液可全部回灌 ,后期再根据实际情况排放处理部分过量的渗滤液。在对渗滤液水量和水质全面直观认识后 ,再对生物反应器填埋场渗滤液处理工艺进行针对性的选择和设计 ,并宜采用物化法处理方式。

Based on the degradation mechanism of municipal solid waste in bioreactor landfill, this paper analyzes the transform trend of leachate and discusses its treatment scheme. At bioreactor landfill, all leachate should be recirculated in the initial stage and then some of it could be treated off-site in the later stage, depending on specific cases. The leachate treatment technology should be selected after overall understanding of leachate quantity and quality, and it should give priority to physico-chemical methods.
